SASH-B ALANCE Specification of Letters Patent.

Patented Dec. 1, 1908.

Application filed March 21, 1908. Serial No. 422,544.

to c'ounter-balance each other so that each sash will act as a balancing weight for the other sash, combined with means for permitting the opening of one sash without the corresponding opening of the other sash, thus enabling the proper ventilation to be obtained at the top of the window frame while the lower sash is down and locked.

A further object of the invention is to so arrange the sash balancing mechanism and combine one of the sashes therewith, that when the top sash is lowered to give ventilation and the lower sash is locked in a closed position, the upper sash will also be locked, thereby preventing both sashes from being opened by unauthorized persons.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawing :Figure 1 is an inside elevation of a window showing the sashes constructed and arranged in ac oordance with this invention, one of the sashes being partially broken out in section. Fig. 2 is a vertical transverse section through the same. Fig. 3 is a view similar to Fig. 1, showing the position of the parts when the upper sash is lowered for ventilation pur poses while the lower sash is locked. Fig. 4c is an enlarged detail perspective view of one of the connections between the lower sash and the sash balancing connection. Fig. 5 is a detail cross section on the line 55 of Fig. 4:.

Referring to the drawings, 1 designates a window frame in which are mounted the lower sash 2 and upper sash 8, said sashes being mounted to slide in the ordinary manner between the other stops and parting beads.

In carrying out the present invention, the sashes 2 and 3 are connected adjacent to the side bars or ambs of the window frame by means of countenbalancing connections 4 which are preferably in the form of chains which run over pulleys 5 mounted in brackets 6 secured to the window frame as shown in the drawings. One end of each connection at is attached to the top of one sash while the other end is attached to the other sash and under the ordinary adjustment of the parts, the length of the connections 4 is just suflicient to effect a closing of the upper sash when the lower sash is carried to its lowermost position. The lower sash is pro vided with a combined lock and lift 7 provided with a catch lock 8 adapted. to engage a keeper 9 on the window sill and also provided with a hook or finger piece 10 by which the said combined lock and lift may be readily manipulated and disconnected from the keeper 9 and to raise the lower sash to the desired elevation.

In order to provide for the relative adjustment of the upper and lower sashes, the lower sash is provided at opposite sides with slides 11 which move vertically through guides 12 secured to the opposite sides of the lower sash 2 as shown in Figs. 1 and 3, the guides 12 being provided with a top flange 13 which extends inwardly and is secured to the upper surface of the meeting rail to the lower sash as illustrated. The slide 11 works upward through an opening in the flange 13 and is provided with a lift portion 14 which is adapted to be engaged by a catch 15 having a lever extension 16 by which said catch may be rocked out of engagement with the lift 14 the catch being pivotally mounted at 17 in a bracket 18 projecting upward from the flange 13 as clearly shown in Fig. 4.

The slide 11 carries a screw-eye 19 at its upper end which has a threaded engagement with the slide and thereby is made adjustable up and down in order to obtain an accurate adjustment of the balance connections 4: so that when one sash is closed, the other sash will be simultaneously brought to a closed position. The slide 11 is also provided at its lower end with a stop hook 19 in the form of a hook which engages the lower end of the guide 12 and limits the upward movement of the slide. Secured to the sides of the window casing are inwardly projecting stops 20 against which the lifts 14 on the slides come in contact When the lower sash is moved upward the required distance.

By rocking the catches 15 out of engagement with the lifts 1 1 of the slides 11 when the sashes are about in the position shown in Fig. 1, the lower sash is left free to be moved downward and said lower sash may then be closed and locked without raising the upper sash which is left in a lowered position as shown in Fig. 3 thereby giving the necessary ventilation at the top of the window. It will also be observed that when the lower sash is looked as shown in Fig. 1, the upper sash is also locked by reason of the fact that the stop hook 19 is caught under the bottom edge of the guide 12 as shown in Fig. 3, thus preventing unauthorized persons from entering at the window. The lower sash is re cessed in its opposite sides as shown at 21 to ment of the slide 11 as shown in Figs. 1

and 3.

Having thus described the invention, what is claimed, is

The combination with sliding window sashes, of a sash-balancing connection attached fixedly at one end to the sash and adjustably connected at the other end to the other sash, a slide and a guide for said slide forming the connection between one end of the sash-balancing connection and the other sash, a hook on the slide adapted to engage the lower end of the guide for limiting the movement of the slide relatively to the sash, and a catch for holding said slide against movement.

In testimony whereof I my signature in presence of two witnesses.

EDWARD J. REILLY.
